Answer
Other metal atoms have different sizes compared to aluminium atoms, which distorts the layers of aluminium atoms. This distortion prevents the layers from sliding over each other, making the alloy harder and thus stronger.
Step 4
Compare the bonding within the chains with the forces between the chains in this polymer.

Answer
In this polymer, the bonding within the chains consists of strong covalent bonds between atoms. In contrast, the forces between the chains are much weaker intermolecular forces. This difference in strength contributes to the polymer's properties.
